A chemical sensor system comprising:
- a package;
- and
- an implantable monitor device, the implantable monitor device comprising an optical chemical sensor;
- wherein the implantable monitor device is disposed within the package;
- a first aqueous solution, the first aqueous solution comprising a solute;
- and
- wherein the first aqueous solution is disposed within the package.
A chemical sensor system comprising:
- a package, the package comprising
- a first chamber;
- a second chamber;
- and
- a seal;
- wherein the seal is disposed separates the first chamber and the second chamber;
- wherein the seal is frangible;
